摘　　要：火成岩油气储层具有分布范围广、地质时代长、不具岩石类型的专属性。火成岩冷却后所形成的晶间孔、收缩孔等原生孔隙不受压实作用的影响 ,与沉积岩储层具有不同的特征。这些特征对寻找深层油气藏具有巨大的优势。根据火成岩油气储层特征 ,形成演化机制、火成岩的时空展布及储层预测等方面存在的问题 ,提出了火成岩油气储层需要加强火成岩岩石学、火山地质、热力学。Igneous rock reservoirs are characterized by their extensive distribution, long geologic time and no exclusiveness of rock types. The primary pores, such as intercrystal pores and shrinkage pores, formed while igneous rocks cool down are not influenced by compaction. These characteristics, being different with that of sedimentary reservoirs, are very favorable for seeking deep oil and gas accumulations. In view of the problems concerning the characteristics, formation and evolution mechanism, time space distribution and prediction of igneous rock reservoirs, it is proposed that igneous petrology, volcanic geology, thermodynamics, physical properties of magma and hydrodynamics, as well as geophysics should be strengthened in study of igneous rock reservoirs.
